From the U.S. Energy Information Administration today:
At the national level, establishments that extract crude oil and natural gas as well as naturally occurring mineral solids, such as coal and ores, collectively referred to as the mining sector in economic data, accounted for about 2% of the U.S. economy last year. In some states, though, the mining sector accounts for a much larger share of the economy. Of the six states where mining comprised more than 10% of the state's economy in 2013, mining growth resulted in five of those states having higher economic growth than the national average.
